Description

Technical Field

[0001] This utility model belongs to the field of industrial automation technology, specifically, it relates to a device and weighing system for identifying the vehicle number of a transport vehicle. Background Technology

[0002] In the steel smelting process, weighing molten iron transport cars is a crucial aspect of production management. Traditional car number identification methods (such as OCR and barcodes) have low recognition rates in high-temperature and high-dust environments, making them unsuitable for practical needs. While RFID technology offers the advantage of non-contact identification, it still presents the following problems in molten iron weighing scenarios: 1. High-temperature environments degrade the performance of RFID tags and antennas. 2. High-dust environments interfere with signal transmission. 3. Vehicle position deviations lead to identification failures. 4. Due to the limitations of the torpedo ladle car body, tags can only be installed on the bottom side of the frame. This can cause adjacent tags to be read incorrectly due to their close proximity. This is currently the main problem with the system. 5. Occasionally, car numbers cannot be identified.

[0003] Therefore, there is an urgent need for a device and weighing system that can improve the recognition rate of vehicle license plate numbers to solve the above problems. Utility Model Content

[0032] Please refer to the following: Figures 1 to 6This invention provides a device for identifying the vehicle registration number of a transport vehicle.

[0033] As one specific embodiment of this utility model, please refer to Figures 1 to 6 A device for identifying the vehicle number of a transport vehicle further includes a slide rail assembly 5. The slide rail assembly 5 includes a slide rail body 51, a first connector 52 disposed on the slide rail body 51, and a second connector 53 disposed on the slide rail body 51.

[0036] In any feasible embodiment, the first connecting member 52 includes a first connecting block, a third magnetic connecting member disposed on the bottom surface of the first connecting block, and a fourth magnetic connecting member fixedly connected to the connection position of the transmission belt. When the upper end surface of the fourth magnetic connecting member approaches the lower end surface of the third magnetic connecting member, the third magnetic connecting member and the fourth magnetic connecting member attract each other. An electric telescopic rod 54 is provided on the first connecting block. One end of the electric telescopic rod 54 is connected to the connecting block, and the other end is detachably connected to the RFID component 1. Specifically, the electric telescopic rod 54 engages with the RFID component 1. More specifically, the other end of the electric telescopic rod 54 is provided with a second slot adapted to the RFID component 1.

[0037] As one specific embodiment of this utility model, please refer to Figures 1 to 6 The RFID component 1 includes an RFID tag installed on the vehicle and an RFID read / write structure 11 mounted on a first connector 52. Specifically, the RFID read / write structure 11 is mounted on the first connector 52 via an electrically telescopic rod 54. The RFID read / write structure 11 is equipped with a signal enhancement module. The RFID read / write structure 11 transmits radio frequency signals through the signal enhancement module to activate the RFID tag and read the vehicle license plate information.

[0038] As one specific embodiment of this utility model, please refer to Figures 1 to 6 The video acquisition module 21 includes a connecting base 211 connected to the electric telescopic pole 54, and a camera 212 fixedly connected to the connecting base 211. An image processing module 22 is housed within the connecting base 211. The image processing module 22 is communicatively connected to the camera 212 and to the data processing component 3.

[0039] A weighing system includes: an RFID component 1, a video recognition component 2, a data processing component 3, and a weighing component 4. The RFID component 1 activates an RFID tag and reads vehicle license plate information, and transmits the read information. The video recognition component 2 includes a video acquisition module 21 and an image processing module 22. The video acquisition module 21 is used to acquire images of the vehicle license plate number to be identified, and the image processing module 22 is used to acquire the vehicle license plate number information. The data processing component 3 is communicatively connected to both the RFID component 1 and the video recognition component 2, and is used to receive the read information transmitted by the RFID component 1 and the acquired information transmitted by the video recognition component 2, and to filter and compare the read and acquired information. The weighing component 4 is communicatively connected to the data processing component 3 and is used to weigh the vehicle.

[0040] In any feasible embodiment, the weighing component 4 is a weighbridge, which includes a weighing platform in the shape of a rectangle. Either side of the weighing platform is arranged parallel to the sliding groove structure of the slide rail body 51.

[0041] The weighing system operates as follows: RFID component 1 transmits an RFID signal through a signal enhancement module to activate the RFID tag and read the vehicle number information. Video recognition component 2 captures the vehicle number (centered) drawn on the side of the torpedo tanker (i.e., transport vehicle) via video and obtains the vehicle number information through an image processing module. Data processing component 3 receives the information transmitted from RFID component 1 and video recognition component 2, performs comparison, filtering, and recognition, and then associates it with the data collected by weighing component 4 to complete vehicle number recognition and weighing recording. Specifically, data processing component 3 performs the following operations: It filters and compares the results from RFID component 1 and video recognition component 2. If the results from both systems match, the result is used directly for weighing. If the results from the two systems do not match, the vehicle numbers of the preceding and following vehicles in the video recognition component 2 result are compared with the results from RFID component 1 to confirm whether the scan is reversed and to determine the correct scan result.

[0042] This utility model provides a device and weighing system for identifying vehicle license plate numbers. Compared with existing technologies, the use of video recognition component 2 avoids the problem of contradictory license plate identification results for adjacent tank trucks. Simultaneously, the results of video recognition component 2 can be compared and supplemented with the results of radio frequency identification component 1 for correction, enabling accurate vehicle plate identification. This solves the problem of occasional failure to identify vehicle plates in RFID technology. Video recognition component 2 completes the identification operation by acquiring images, achieving high-precision and high-stability vehicle plate identification even in high-temperature and high-dust environments. It also solves the problem of contradictory license plate identification results for adjacent tank trucks due to their labels being installed too close together, a problem common in RFID technology. The spacing between receiving radio frequency identification component 1 and video recognition component 2, their relative positions on the slide rail body 51, and their relative heights can be adjusted according to usage needs, effectively expanding the applicability and ease of use of this device and system.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
